Loading a 1024-byte q3history file will fill the whole consoleSaveBuffer
leaving no space for a string terminator. Com_Parse will read at least
one byte beyond the end of consoleSaveBuffer. The written console
history file can only be 1023 bytes (enforced by Q_strcat) so don't
allow loading size of 1024.
If switching to a mod with a shorter q3history file, the data in
consoleSaveBuffer that isn't overwritten will be parsed. So always
add a string terminator.
String not terminated reported by David "devnexen" CARLIER.
